JS_GetExternalStringClosure 编辑
Obsolete since JSAPI 13
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
This article covers features introduced in SpiderMonkey 6
Returns the string closure stored in a JSString created by calling JS_NewExternalStringWithClosure.
Syntax
void *
JS_GetExternalStringClosure(JSContext *cx, JSString *str);
| Name | Type | Description |
|---|---|---|
cx | JSContext * | The context from which to retrieve the closure for a string. Requires request. In a JS_THREADSAFE build, the caller must be in a request on this JSContext. |
str | JSString * | The string for which to return the closure. The result is NULL if the external string was created without one (that is, by calling JS_NewExternalString rather than JS_NewExternalStringWithClosure). |
Description
To determine if a string was created as an external string, you can call JS_IsExternalString.
